mdeesnuts:I've had a standup desk for a year. Curious side effect is I don't usually sit anymore unless you're supposed to; eating, watching TV, etc. Can't sit in a waiting room, waiting for a table at a restaurant, I stand rather than sit at a bar. It's strange but I don't feel the need to sit unless I am actually tired.

I've tried a stand up desk, got it was horrible on my feet and strangely my hips. If I'm going to be on my feet for hours at a time, I want to be doing a fair amount of walking, which is surprisingly easier on my system that standing in place for long periods.
